Please help me!
the finishing time for a runner completing the 200 meter dash is affected by the tail wind speed, s. the change, t, in a runner's performance is modeled by the function below t= 0.0119s^2 - 0.38s - 0.0003 predict the change in a runners finishing time with a wind speed of 4 meters/ seconds.
Note: a negative answer means the runner finishes with a lower time. round to the nearest hundredth.

Using the given equation, replace s with 4 and solve for t:

t = 0.0119s^2 - 0.38s -0.0003

t = 0.0119(4)^2 - 0.38(4) - 0.0003

t = 0.0119(16) - 1.52 - 0.0003

t = 0.1904 - 1.52 - 0.0003

t = -1.3299

Rounded to the nearest hundredth t = -1.33

This means the runner would finish 1.33 seconds faster. ( Lower time)
